The goal of this set of analyses is to take a deeper dive into the 2019 Seattle calls for service data. To follow up on the preliminary exploratory analysis, we will focus on three types of cases - Disturbance, Suspicious person, and trespass - as well as one type of case resolution - No possible action possible. The questions we want to address here include the following?

  1. Where did the three types of cases occur?
  2. How were these three types of cases resolved?
  3. Does the type of resolution differ by location?
  4. What types of cases were cleared without police action?
  5. Where are the cases that were resolved without police action located?
